Transgenerational trauma is the psychological and physiological effects that the trauma experienced by people has on subsequent generations in that group. The primary mode of transmission is the shared family environment of the infant causing psychological, behavioral and social changes in the individual.
The genetics of social behavior is an area of research that attempts to address the question of the role that genes play in modulating the neural circuits in the brain which influence social behavior. Model genetic species, such as D.melanogaster (common fruit fly) and Apis mellifera (honey bee), have been rigorously studied and proven to be ...
In conditions of social stress however, the up-regulation of pro-inflammatory gene expression prepares the body to better deal with bodily injury and bacterial infection which is more likely under conditions of social stress either through hostile human contact, or increased predatory vulnerability due to separation from the social group.

Similarly, in observational studies of parent-child behavioural transmission, for example, it is impossible to know if the transmission is due to genetic or environmental influences, due to the problem of passive gene–environment correlation. [53]
Behavioral epigenetics is the field of study examining the role of epigenetics in shaping animal and human behavior. [1] It seeks to explain how nurture shapes nature, [2] where nature refers to biological heredity [3] and nurture refers to virtually everything that occurs during the life-span (e.g., social-experience, diet and nutrition, and exposure to toxins).

Human genetics is the study of inheritance as it occurs in human beings.Human genetics encompasses a variety of overlapping fields including: classical genetics, cytogenetics, molecular genetics, biochemical genetics, genomics, population genetics, developmental genetics, clinical genetics, and genetic counseling.
For example, suntanned skin derives from the interaction between a person's genotype and sunlight; [4] thus, suntans are not passed on to people's children. However, some people tan more easily than others, due to differences in their genotype: [ 5 ] a striking example is people with the inherited trait of albinism , who do not tan at all and ...
